I have long been a proponent of right-side navigation--primarily for
frames, but it makes just as much sense for frameless menus. The big
advantage to right-side navigation is ergonomic. Your mouse hand has to
travel less when moving between menu options and the scroll bar. In
framed sites, it puts the two scroll bars (the one for the menu frame
and the one for the main frame) on the same side of the browser window.
With the menu in a left-side frame, the user is forced to sweep the
mouse clear across the width of the browser window to scroll through the
content window and then back to the menu window.

I don't know of any studies. This has been my personal preference for a
long time.
